nice pedal. this thing is not true bypass so beware. i think there is a true-bypass version for like 30 bux more...what a rip. but wow. everyone who has heard me play through this can't believe how huge it sounds. they always look immediately to the floor and give me a crazy look like "what is that wickedness coming from your cab?" it says in the manual that it does not track the octave and sub-octave parameters. you will lose a lot of thickness tracking. I'm going to experiment with some mics throughout the room cuz i heard it thru a camcorder mic and it sounded better than thru my Korg D1600xd 16 trak. (The head of the amp was output directly to the recorder.) i read a review that said there are only 2 good settings, but if you play slower, spacy grooves or stuff with drum machines...anything where the bass has some freedom, you will like this...i even use it on a fast song for the guitar solo...so if you're shy about your tone and experiementing, maybe this isn't for you. I have a ton of settings marked and ive had it 2 weeks. great surging wah effects...turbo charged distortion effects...String sounds...I have layred massive chords using a boss loop station and that sounds incredible. You will easily find a sound that makes you go "I have totally heard this before" (or wanted to hear it) Susutain is a little weak, but overall, straight wicked. Will kill your bass and bring it back to life, if you're into that. I gave it a 4 because of the tracking issue and because the housing is not as sturdy as i had expected. I guess for the lack of sustain, too. For the price, it BETTER sound this good...and it does. It will be hard to be disappointed if you already expect the small problems of tracking and sustain.
